When Sean Rogerson, as Aleister, says the special code phrase "I am the lock" and Kiara Glasco, as Savannah, responds "And I'm the key", it is a reversal of the dialogue in the 1976 Dean R. Koontz mind-control thriller novel, "Night Chills", in which the man in charge boldly proclaimed that he was the key, and the subject meekly answered that he/she was the lock. As in this show, set in Bear Valley, "Night Chills" took place in a secluded town, Black Water. Unlike this show, unfortunately, "Night Chills" never got filmed.
